[Why]
Since dmub_rb_cmds are not initialized to 0,
the header is filled with invalid data.
This is causing issues on the fw side.
[How]
Initialize dmub_rb_cmd unions to 0.

[Why]
Cached backlight is never being updated since panel_cntl specific
registers were moved from abm to panel_cntl.
[How]
Update cached backlight in set_abm_immediate_disable as what we used to
do. Also, update the priority of backlight restore mechanism so that
cached backlight has the highest priority since it is always correct.

[Why]
enable ODM on eDP panel with ABM will result in color difference
on the panel due to only one ABM module to set one pipe.
[How]
Block ABM in case of ODM enabled on eDP.

[Why]
When hotplug a HDMI monitor during entering S0i3 or DPMSOFF state due to
entering infinite loop when calling vbios to program pixel clocks. In
this scenario, pll is enabled but phy is not, and there is not a
programing guide for this case.
[How]
Before we having the proper programing guide, before disable pll, doing
a phy enable and disable to avoid the issue.

[Why]
Some function pointers in the hwss function pointer table are
meant to be hw sequencer entry points to be called from dc.
However some of those function pointers are not meant to
be entry points, but instead used as a code reuse/inheritance
tool called directly by other hwss functions, not by dc.
Therefore, we want a more clear separation of which functions
we determine to be interface functions vs the functions we
use within hwss.
[How]
DC interface functions will be stored in:
struct hw_sequencer_funcs
Functions used within HWSS will be stored in:
struct hwseq_private_funcs

[Why]
It is becoming increasingly hard to figure out which
function is called on the different DCN versions
[How]
1. Make function pointer table init in its own init.c file
2. Remove other scenarios in hwseq.c file that need to
include headers of other DCN versions. (If needed,
it should have been done via the function pointers)
